Why start a prenatal supplement 3 months before trying to conceive

What women in the English-speaking world have known for 20 years, and what we are (finally) starting to talk about in France.

In France, a prenatal supplement is generally started when the test comes back positive.

In the United States, the United Kingdom and Canada, it is started 3 months before trying.

This is what the WHO, ANSES and a growing number of fertility experts recommend, for one simple biological reason:

Everything happens before the pregnancy test.

The key points

The critical window happens before you even know

The baby's neural tube (brain + spinal cord) closes between day 21 and day 28 of pregnancy — that is, before a missed period, before a test, before any sign. This is why having your folate reserves already at the right level at this point matters.
Your eggs mature over 90 days

The egg that will be fertilised this month began its maturation 3 months ago. During this window, it is sensitive to your diet, your oxidative stress, and your levels of CoQ10, zinc, selenium, vitamin D, and omega-3.
Optimising these intakes in advance = supporting egg quality, and therefore the chances of conception and a healthy pregnancy.
Addressing deficiencies takes time

A deficiency in iron, vitamin D or iodine cannot be corrected in 2 weeks. Starting 3 months ahead allows you to build up reserves — for you (energy, immunity, mood) and for your baby.
Because diet isn't always enough

Pregnancy and breastfeeding increase the need for key nutrients (DHA, iodine, iron, vitamin D…). Supplementation helps to fill the gaps that diet alone does not always cover.
The simple solution: a well-designed 3-in-1 prenatal

A multivitamin + DHA + choline in active forms and relevant doses simplifies your routine — whilst remaining adaptable (iron and magnesium can be added if needed).
